To all Whom/.it mag/concern:

Beit known that I, HENRY POLICAN, a citizen of the United States, lately residing in Paterson, in the county of Passaic and State of New Jersey, and noWin the city and county of Philadelphia, inthe State of Pennsylvania, Y

have invented certain new and useful improvements in jacquard or dobby cards and the art and means of connecting them to each hereby declare the `following specication and the accompanying drawings are sufficiently full and clear to enable others skilled in the art to make and use the said invention. I5

' known as jacquard and dobby cards used in weaving machinery to control the operation of needles or wires that regulate the action of the j acquard-harness,` thro ugh which j the warp-threads pass, so as to prod-uce'figures in the woven product, 'and relates kparticularly to the connecting of the cards together lin ilexible series, and has for its objects the morev expeditious fastening of them, greater d urability of the connections, andy betlter accuracy of register of the apertures in the several cards with the projecting points.

upon .the weavingnmachinery ywhereby the .cards are operated. To effect these objects,

this invention may be briefly stated to consist in making perforations in the cardsin lines of uniform distances from the ends of thecards and connecting'tapes coated on one side with adhesive cement to the cards upon opposite sides of the cards on the-lines ofthe p'erforations and applying pressure to the tapes, so that the tapes adhere to 'each other in theV perforations and hold securely on the cards, and the tapes are also cemented to each other at practice of connecting jacquard and dobby cards has been bylacing or-y sewing 'cords throughapertu'r'es formed in them,whichlcords lengthen'ed and shortened with hygrometric vchanges of the'atmosphere fand varied the distances between .thev cards and, besides being: flexible vin the direction of i 5o the length of the cards, were susceptible of v lateral motion, which produced undue wear other inseries, of which improvement I do This invention relates to the pattern-cards.

the interstices between the cards, forming;

between the pins or lpoints of the weaving;

l HENRY PONGAN, or PrnLnELPniA,rENnsYLvANI, AssIeNoR oni'lonn'- machine'and the edges offthe apertures in the cards, thus i'mpairing the registering of the cards with the needles or wires of the loom controlling the harness and seriously impairi ing the usefulness and durability of the cards. ,My invention to'lobviate these objections is made and practiced as follows, referring to the accompanying drawings, in which- Figure 1 shows in dat view three cards` as made to be united in series. Fig. 2 shows one of the cards in enlarged section on the line marked as a: on Fig. 1. Fig. 3 shows in flat view three cards as united in series by tapes. Fig. 1iv shows an enlarged section of two of the `cards so united, drawn in the plane indicated by the line y' y on Fig. 3. Fig. la shows in enlarged view a part of Fig. 4. The cards (marked l) are ofthe usual rectangular form, having apertures 2 for receiving the wires controlliu g theha'rness and warpf threads and apertures 3 for registering with ates them. In these respects lthey do not differ from cards asnowvin general use.

Aper- 'tures 4: are made injlines across each card, P

and the cards are held in proper position of register with each yother Vby meansof the aperturesf, fitting onsuitahle pins. Tapes G and 7are applied to opposite sides ofv the cardsV 'lon the lines of the apertures 4, with cement upon the opposed surfacesof the tapes, and e 'V V pres-Sed rmly UPU-n the. Cldsfby elastic press. Y Y,

ing padsfor rollers 8 and 9whic'h force'the tapesand 7 into contact with each other ini .y

rthe .apertures 4;, as shown in Figa, and aty `the interstices 10 betweeny the cards, where the tapes adhere firmly to each other and also adhere' to thersurfaces of the-cardsl. "The tapes 6 and 7 form' iiexiblehinges between thei andthe edges of the cards, as is the case with v4.lacing-cords', anyinaccuracy andwear from f.

suchfcauses are avoided. t The cement used should4 besuch as will' notV make the tapes rigid or brittle at thevpo'rtion ICO belwreenV the cards, and 1 any `cement having Y 9S- having no motionor friction between them i i strong adhesive properties with ay lexible property answers. I have` used a cement 1 known commercially as diachlon or leadseries of jacquard or dobby cards, having interspaces between the cards, lines of perforations through the cards, and tapes cemented upon opposite sides of the cards, with adhesion oi' the tapes to each other in the apertures, and at the interspaces between the cards, as and for the purpose set forth.

HENRY PoLIoAN.
